Serial No. 504,984.

This invention relates to machines for shaping and flanging bodies of sheet material, and has for its main object and feature the provision of means of a simple and reliable character for effecting said operation.

ln the accompanying drawings the invention is disclosed in a concrete and preferred form in which Fig. 1 is a plan view of a device embodying the invention;

F ig. 2 is a vertical sectional view substantially on the plane of line 2-2 of F ig. 1, with the jaws shown in open position;

Fig. 8 is a view similar to Fig. 2, with the jaws shown in closed position but before Hanging takes place;

Fig. 4f is an enlarged view of parts of Fig. 3 showing the final step of flanging the body of sheet material;

Fig. 5 is a horizontal sectional view substantially on the plane of line 5 5 of Fio. 2; and

Fig. 6 is a sectional view similar to Fig. 5, substantially on the plane of line 6--6 of The body 1 of sheet material is supported on its end by supporting means 2 when introduced between contractible outer jaws 3 and expansible inner jaws et, and it will be understood that by bringing said aws toward each other the body will be shaped, in this instance corrugated. Also that by moving the supporting means outwardly, ledge 5 will, as indicated in Fig. et, flange the supported end of the body, as indicated at 6.

rlhe outer jaws are generally segment-alshape, and grouped around them is a plurality of cylinders 7, suitably supported in the framework, each of which cylinders is provided with a fluid-actuated piston S that carries an outer jaw. By introducing fluid pressure in one side or the other of a piston, it will be seen that the aw carried by it will be moved by direct thrust of said piston.

The inner aws are slidably mounted on uprights or posts 9 carried by the framework and have elongated slots 10 admitting of outward and inward movement of said jaws with respect to said posts. It will be seen that supporting members \2 are located at the lower end of the inner aws, and that said members 2 are likewise provided with slots 11 that permit them to be moved with respect to posts 9. lt will be seen, however, that supporting members 2 are articulated independently of the inner jaws, and that, in the construction here shown, the supporting members slide on the framework and that the lower ends of the inner jaws slide on the supporting meinbers. 12 indicates a cylinder disposed axially of the body to be shaped or centrally of the machine, and this cylinder contains a piston 13, the shaft 14 of which latter extends up inside the inner jaws. Connecting said shaft and the inner jaws are links 15, each of which is pivotally supported at 16 and V17' on the shaft and an inner jaw respectively. lt will now be understood that movement of piston 13 and shaft 14: in response to fluid pressure vin one direction will move the inner jaws outwardly and that, upon fluid pressure being exerted in a reverse direction, the inner aws will move inwardly. It will further be seen that the link connection between the piston shaft and an inner aw virtually constitutes a toggle, the thrust of which is powerful. Springs as 18 may be employed to assist in retracting the inner jaws and the supporting members. Carried by piston shaftl is a cam 19 or a taper surface that coacts with a surface 2O on the supporting means so that, upon engagement of said surfaces, said supporting means, which are in segmental pieces like the inner jaws, will move outwardly. Cylinders 7 and 12 are each pro-v vided with two pipes for the admission and exhaust of fluid pressure, said pipes being indicated at 21 and 22.

A body 1 of sheet material is placed in position on the supporting means, and fluid pressure is admitted to all the cylinders 7 and 12, by means of one or more suitable control valves, through pipes 21, Huid on the other side of the pistons being exhausted through 22. The effect of this is to move he inner and outer jaws toward each other to corrugate the body, the continued movement of piston shaft 14, thereafter, acting to move the supporting means to thereafter flange the body and to move the inner and outer jaws f eo still closer together. The iiow of fluid pressure is now reversed and fluid is introduced through pipes 22 and exhausted through 21 thereby reversing the movement and releasing the body.
